Külüg Khan (Mongolian: Hülüg Khaan, Хөлөг хаан, Külüg qaγan), born Khayishan (also spelled Khayisan, Mongolian: Хайсан, meaning "wall"), also known by the temple name Wuzong (Emperor Wuzong of Yuan, Chinese: 元武宗; pinyin: Yuán Wǔzōng; Wade–Giles: Wu-Tsung) (August 4, 1281 – January 27, 1311), was an emperor of the Yuan dynasty. Apart from Emperor of China, he is regarded as the seventh Great Khan of the Mongol Empire or Mongols, although it was only nominal due to the division of the empire. His name means "warrior Khan or fine horse Khan" in the Mongolian language.

He was the first son of Darmabala and Dagi of the influential Khunggirad clan, and the full brother of Ayurbarwada. He was sent to Mongolia to assume an army that defended the western front of the Yuan against Kaidu, de-facto ruler of the Chagatai Khanate, and other princes in Central Asia under him. In 1289, Khayishan's force was nearly routed and the Kipchak commander, Tutugh, rescued him from capture by Kaidu's army. In 1301 he clashed with Kaidu, who died from a battle wound. In recognition of the great success, Külüg Khan was given the title of Prince Huaining (懷寧王) in 1304.
